Izikulufu Zokuguqula Insimbi Engagqwali ze-AOZHAN: Izixazululo Eziphezulu Zemishini Yamandla Enamandla Aphezulu

Izinto Ezibalulekile Okufanele Uzicabangele​

Ukuqonda Izicelo Nezidingo Zesikulufu Se-Transformer​

Izicelo Ezibalulekile Ezinhlelweni Zamandla​

Izikulufo ze-transformer zisebenza imisebenzi eminingi ebalulekile engqalasizinda kagesi. Kuma-transformer anamandla amakhulu, lezi ziqinisekiso zibalulekile ekuhlanganiseni izinhlangano zamathangi nezembozo, ikakhulukazi ezindaweni eziseduze nama-bushings ane-voltage ephansi lapho imisinga elahlekile ingadala khona ukushisa okukhulu. Ucwaningo lwethu lukhombisile ukuthi ku-transformer engu-420 MVA, engu-20/230 kV, izikulufo eziseduze nama-bushings ane-voltage ephansi zingaba nokushisa okukhulu, amazinga okushisa afinyelela ku-155°C.​

Izinhlelo zokusebenza ze-high-voltage Izikulufo ezidingekayo ezingamelana nokucindezeleka okukhulu kukagesi ngenkathi zigcina ubuqotho bomshini. Izikulufo ze-AOZHAN transformer zenzelwe ukusebenza ngokuphephile ezinhlelweni ezilinganiselwe kufika ku-72kV, njengoba kuqinisekiswe ukuhlolwa kwe-IEC 62271-1 ​Izidingo zikagesi zalezi zinhlelo zokusebenza azihlanganisi nje kuphela amandla omshini kodwa futhi nekhono lokugcina ukumelana okuphansi kukagesi nokuvimbela ukuphuma kwe-corona.​

Ngoba ukufakwa kwangaphandle, izikulufo zethu zensimbi engagqwali zinikeza isivikelo esiyingqayizivele ezicini zemvelo. Izinto zokwakha izindlu ze-transformer esizisebenzisayo, njenge-HCEP (High Creepage and Erosion Resistant Polymer), ziqinisekisa ukusebenza okuthembekile kakhulu ezindaweni ezimanzi noma ezinomswakama zangaphandle. ​Izingxenye zethu zokumisa umhlabathi zenziwe ngokunemba kusetshenziswa i-alloy yethusi neyethusi eqhuba kahle ukuqinisekisa ukusebenza kahle kukagesi, ukumelana nokugqwala, kanye nokuqina kwesikhathi eside ezindaweni zangaphandle ezine-voltage ephezulu. ​.​

Ku- izinhlelo zokusebenza zekhabhinethi yokulawula, izikulufu zethu kumele zihlangabezane nezindinganiso ezithile zokuvikela imvelo. Sinikeza izixazululo ezihambisana nezilinganiso ze-NEMA Type 3R kanye ne-IP32, ezineziqongo zezivikelo ze-drip kanye nezinhlangothi ezingenamthungo ​Izimbozo ezisuswayo ezishelelayo ziboshwe ngezikulufo zensimbi eziboshwe eceleni komphetho ongezansi, okunikeza ukufinyelela okulula ngenkathi kugcinwa ukuvikelwa kwemvelo ​.​

Ukukhethwa Kwezinto Ezibalulekile kanye Nezindlela Zokusebenza​

• I-SUS304 Insimbi Engagqwali (A2-70): Lena inketho yethu eguquguqukayo kakhulu, equkethe i-18-20% chromium kanye ne-8-12% nickel ​. Isikhundla se-A2-70 sibonisa amandla okudonsa okungenani angu-700 MPa. I-SUS304 inikeza ukumelana okuhle kakhulu kokugqwala futhi ifaneleka kakhulu ekusetshenzisweni kwangaphakathi nangaphandle lapho ukuchayeka kwe-chloride kuncane khona. Inikeza ukubekezelela okuphezulu kwe-chloride okungaba ngu-200 ppm ​.​

• I-SUS316 Insimbi Engagqwali (A4-80): Inketho yethu ye-premium marine-grade iqukethe i-16-18% chromium, 10-14% nickel, kanye ne-2-3% molybdenum ​. Ukwengezwa kwe-molybdenum kunikeza ukumelana okuphezulu ekubhobozeni okubangelwa yi-chloride kanye nokugqwala kwemifantu. Igama elithi A4-80 libonisa amandla amancane okudonswa angu-800 MPa. I-SUS316 inikeza ukubekezelela i-chloride kufika ku-2000 ppm, okwenza kube kuhle kakhulu ekufakweni kogu kanye nasezindaweni zokucubungula amakhemikhali. ​.​

• Womabili la mazinga anikeza izakhiwo ezinhle kakhulu zemishini, okuhlanganisa amandla amancane okukhiqiza angu-205 MPa kanye nokwelulwa okuncane okungu-40% ​Izinto azinamagnetic esimweni sazo esivaliwe, okubalulekile ekusetshenzisweni lapho kufanele kugwenywe khona ukuphazamiseka kwamagnetic ​.

Imininingwane Yobuchwepheshe kanye Nedatha Yokusebenza​

Izikulufo ze-AOZHAN transformer zenzelwe ukucaciswa kobuchwepheshe okunembile ukuqinisekisa ukusebenza okulinganayo nokuthembeka. Imikhiqizo yethu ihambisana nezindinganiso zomhlaba wonke ezifaka phakathi i-ISO 3506 kanye ne-GB/T 3098.6 yezinamathiselo zensimbi engagqwali.​

Ithebula elilandelayo linikeza imininingwane ebalulekile yobuchwepheshe yemikhiqizo yethu eyinhloko yezikulufo ze-transformer:​

Ukuvimbela Izindawo Ezishisayo Nokuphathwa Kokushisa​

Enye yezinselele ezibaluleke kakhulu ekwakhiweni kwezikulufo ze-transformer ukuvimbela izindawo ezishisayo ezibangelwa imisinga elahlekile. Ucwaningo olwenziwe kuma-transformer kagesi lubonise ukuthi imisinga elahlekile ezakhiweni zesakhiwo eduze kwama-bushings anomsinga ophezulu ingadala ukushisa okukhulu, okuholela ezindaweni ezishisayo kuma-screws ajoyina ithangi futhi amboze.​

I-AOZHAN isungule ikhambi elisha isebenzisa izimbobo zethusi ukunciphisa lezi zindawo ezishisayo. Esifundweni se-transformer engu-420 MVA, ikhambi lethu lehlise amazinga okushisa aphezulu kusukela ku-155°C kuya ku-80°C ngemuva kokufaka izimbobo zethusi kuzo zonke izikulufo zokumboza. Lokhu kusho ukwehla kwezinga lokushisa cishe ngo-50%, okuthuthukisa kakhulu ukuthembeka kanye nokuphila kwesikhathi se-transformer.​

Isixazululo sihilela ukusebenzisa i-copper sill njengebhuloho lokuqondisa phakathi kwethangi nesembozo, kuhlanganiswe nezikulufo zensimbi engagqwali (A-316), ama-washer aseBelleville nama-washer ayisicaba enziwe ngezinto ezilwa nomagnetic, kanye nama-nuts ensimbi engagqwali. Le nhlanganisela iqinisekisa kokubili ukuhanjiswa kukagesi kanye namandla omshini ngenkathi kunciphisa imiphumela yokushisa.​

Izidingo Zokufakwa Ne-Torque​

Ukufakwa kahle kwezikulufo ze-transformer kubalulekile ekusebenzeni kwazo kwesikhathi eside. I-AOZHAN inikeza imininingwane eningiliziwe ye-torque ngokusekelwe ezindinganisweni zomhlaba wonke kanye nezakhiwo zezinto ezibonakalayo. Izikulufo zethu kumele ziqiniswe kusetshenziswa ama-torque wrench ngokwezindinganiso zomklamo, futhi uma kungekho torque ethile ehambisana noMthetho, kufanele kulandelwe amanani ajwayelekile embonini.​

Ithebula elilandelayo linikeza amanani e-torque anconyiwe ezikulufini zethu ze-transformer:​

Ngokuxhumanisa kukagesi, sincoma amanani e-torque angu-250-350 lb-in (28-40 N·m) ngokuxhumanisa okukhulu kanye no-50-75 lb-in (6-8 N·m) ngezikulufo ezingu-1/4" ​Kubalulekile ukuqaphela ukuthi amanani e-torque angempela kumele alungiswe ngokusekelwe ekilasini lokusebenza kwebholidi, isimo sobuso, kanye nohlobo lwe-washer.​

Izinto Ezicatshangelwayo Nokuvikelwa Kwemvelo​

Izikulufo ze-transformer ezisetshenziswa ngaphandle kumele zibhekane nezimo zemvelo ezinzima. Izikulufo zensimbi engagqwali ze-AOZHAN zenzelwe ukunikeza ukumelana okungavamile nokugqwala, imisebe ye-UV, kanye nokushintshashintsha kwezinga lokushisa. Izikulufo zethu ze-SUS316 zezinga lolwandle zidlule ukuhlolwa kokufuthwa kukasawoti kwamahora angu-500 (ukuthobela i-ASTM B117) futhi zihlangabezana nezidingo zokukhuthazela kokudlidliza ngokwezindinganiso ze-IEC 60068-2.​

Ezindaweni ezinomswakama ophezulu, izinto zethu zokwakha izindlu ze-transformer ziqinisekisa ukusebenza okuthembekile ngamabanga anele okuhamba ukuze kuhlangatshezwane nezidingo zamakhasimende ​Izinto esizisebenzisayo zivikela ekungeneni komswakama, ukuchayeka kumakhemikhali, kanye nokushintshashintsha okukhulu kwezinga lokushisa.​

Izindinganiso Zekhwalithi kanye Nezitifiketi​

Ngezinhlelo zokusebenza ze-transformer, imikhiqizo yethu yenzelwe ukuhlangabezana nezidingo zochungechunge lwe-EN 61558 lwama-transformer ane-voltage ephansi kanye nochungechunge lwe-EN 60076 lwama-transformer anamandla aphakathi namakhulu. ​Sisebenzisana nezinhlangano ezigunyaziwe ezazisiwe njenge-TÜV kanye ne-CESI ukuqinisekisa ukuthi imikhiqizo yethu ihlangabezana nazo zonke izidingo zokuphepha nokusebenza ezidingekayo. ​.​
